A cutting device for casting gears

Abstract

The invention discloses a cutting device for casting a gear. The cutting device comprises a fixing mechanism and a cutting mechanism, wherein the fixing mechanism and the cutting mechanism are used in a matched manner. The fixing mechanism comprises a workbench, and the workbench is provided with a fixing shaft and pressing devices, wherein the fixing shaft and the pressing devices are used in a matched manner. Each pressing device comprises a supporting piece, each supporting piece supports a fixing piece through a rotating shaft, each fixing piece can rotate around the corresponding rotating shaft and is provided with a screw, and each screw penetrates through the corresponding fixing piece to abut against the corresponding rotating shaft. The cutting device is simple in structure, the gear is placed in the fixing shaft, the pressing devices fix the gear again, and the gear is fixed firmly; and besides, the fixing pieces can rotate around the rotating shafts, different types of gears can be fixed, and thus machining of the cutting mechanism is facilitated.

Description

technical field [0001] The invention relates to a cutting device for casting gear blanks, belonging to the technical field of machining. Background technique [0002] Gears are wheel-shaped mechanical parts that rely on the meshing of teeth to transmit torque. The gear can realize the functions of changing the speed and torque, changing the direction of movement and changing the form of movement through transmission with other toothed mechanical parts (such as another gear, rack, worm). Due to the advantages of high transmission efficiency, accurate transmission ratio, and large power range, gear mechanisms are widely used in industrial products, and their design and manufacturing level directly affect the quality of industrial products. The gear teeth interlock with each other to drive the other gear to rotate to transmit power.

Problems solved by technology

[0003] When manufacturing gears, the traditional blank cutting is to place the blank horizontally on the cutting table. When cutting, the debris at the cutting site will be scattered on the workbench. When the tool is cutting, it is affected by the debris and is not only easy to damage. The cutting tool will also make the cutting surface uneven and fail to meet the expected cutting requirements; the cutting length is fixed, and the cutting length cannot be changed according to actual needs

It has been improved. The cutting piece is placed in the vertical fixing mechanism for cutting, and then a channel is set to discharge the chipping, which solves the problem that the cutting chipping affects the cutting quality, but there are still deficiencies. The length is fixed, which cannot meet the cutting requirements of different types of gear blanks
